It comes as the Australian Institute of Criminology today releases a report saying that half of the nation's 20,000 to 30,000 vegetation fires each year are deliberately lit, costing the community $1.6 billion per year.

Mr Baillieu says the estimated $100 million cost of last week's heatwave has tarnished the state's reputation.

About 1,300 train services were cancelled leading to an increase in the number of people not showing up for work, and hundreds of building sites across Victoria came to a standstill in the sweltering conditions.

Mr Baillieu says the state's inability to cope with the extreme conditions is a direct result of the Brumby Government failing to invest in infrastructure.

"We have lost wages, we have lost stock, we've lost sales, we've lost reputation, we've lost capacity and the Government has to take responsibility for that and understand that there is a cost to it and more should have been done to prevent these sort of things from happening," he said.
